The answer depends entirely upon the scenario. Are you dealing with AC or DC? Does your circuit contain passive components or both passive and active components?

For example, if you a simply dealing with a resistive DC circuit, you can derive your answer from Ohm's law, V = IR. Rearranging for current, I = V/R, so if you double the voltage, the current is subsequently doubled.

If the resistance in a circuit is doubled while the voltage remains the constant the current is?

It is halved. coz voltage=current * resistance


What happens to a parallel circuit resistance if the voltage applied is doubled?

In a parallel circuit, the total resistance remains the same when the voltage applied is doubled. Each branch in the parallel circuit will experience the same increase in voltage, but their individual resistances will remain constant.


What happens to the resistance when the frequency is doubled?

When the frequency is doubled, the resistance of a circuit remains unchanged. Resistance in a circuit is independent of frequency and is determined by the material and physical dimensions of the resistor.


What happens to the current when the voltage is doubled and the resistance is constant?

If the voltage is doubled and the resistance is constant, Ohm's Law states that the current will also double. This is because the relationship between voltage, current, and resistance is linear, and increasing the voltage will directly increase the current flow.


What happens when you halve the resistance in a circuit when voltage remain constant?

Since resistance is the ratio of voltage to current, we can say that halving the resistance will result in twice the current.


What happens in a series circuit if the resistance is halved?

If you add a second resistor, the resistance of series circuit will increase.


What happens to the current flowing in a circuit if its resistance is doubled?

Using Ohms Law: V = I x R, where V (Voltage), I (Current), and R (Resistance). re-arranging: V/R = I Therefore if you double both the Voltage and the Resistance, the current remains unchanged.Current = Voltage / Resistance. If both resistance and voltage double the current remains the same.


When a dead short occur what happens to circuit resistance?

The circuit resistance is likely to gradually drop and in such case it will cause the circuit to burn down.


When resistance is in a circuit what happens to the current?

When you add resistance to a circuit, current goes down. Ohm's Law: current = voltage divided by resistance.


What happens to the current of the wire when the length increases?

resistance is directly proportional to wire length and inversely proportional to wire cross-sectional area. In other words, If the wire length is doubled, the resistance is doubled too. If the wire diameter is doubled, the resistance will reduce to 1/4 of the original resistance.


What happens if you shorten the resistance wire in a circuit?

It shortens


What Happens To The Overall Current Of The Circuit If The Number Of Receivers (and Thus The Number Of Branches) Is Doubled?

If the number of receivers (branches) in a circuit is doubled, the overall current of the circuit would also double, assuming that the voltage remains constant. This is because current is divided equally among the branches in a series circuit, so increasing the number of branches would result in each branch carrying less current if the overall current remained the same.
